Description

Comprehensive Grounding and Protection of Communication Sites

One-Day Training Seminar

Course Summary

A high-integrity grounding system is the single most effective means of assuring quality power distribution with a minimum risk exposure to transient spikes, noise, and lightning. This one-day course describes how all of the key elements of a communications site grounding and protection system function with emphasis on single point grounding techniques.

Who Should Attend

This course is designed for the communications professional whose job responsibilities include working with AC and DC systems powering critical equipment.

A prerequisite for attendance is a basic understanding of electrical theory and Ohm's law.

What to Expect

The class meets from 8 am to 5 pm with complimentary catered continental breakfast, lunch and refreshment breaks to give extra time for student-faculty interaction.

Each student will receive a course manual that includes the figures, tables and graphs discussed during the presentation.

Additional Training

Upon request, a second day of hands-on Site Inspection Training may be arranged for private groups at a discount following this course. Site Inspection Training takes place at a client facility, where students will learn the principles and techniques to identify deficiencies in a site’s electrical, grounding, and protection systems including visual inspection and using various field measurement instruments.
